In EWS, you can create a draft like this:
<tns:CreateItem MessageDisposition="SaveOnly">
<tns:Items>
<t:Message>
<t:ItemClass>IPM.Note</t:ItemClass>
<t:Subject>subject</t:Subject>
<t:Body BodyType="HTML">body</t:Body>
<t:IsRead>false</t:IsRead>
</t:Message>
</tns:Items>
</tns:CreateItem>
What do I need to add to create a regular message instead of a draft, as the code above does (using SOAP messages, not the Managed API)?
